NT OFFICE ASSIGNAOR TO ACME CARD SYSTEM COlVIf .'PANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS VISIBLE INDEX This invention relates to visible indexes, and refers more particularly to visible index cards `mounted in overlapping relation on a L frame. Y "g1 VThe specific embodiment of the present 1nvention resides in having the cards removably attached to hinges7 which latter may themselves constitute hangers, or which may (q be auxiliary to and removably mounted on 10 they hangers. Thehinge element of the present invention is provided with means whereby the cards are supported on or adJacent their side edges. Each hinge element per se (M, takes the form of two opposite side card supporting plates provided with card holding means and connected by means of a substantially rigid connecting piece. In other words, the connecting link between each pair of side M plates is constructed of non-iiexible metal.

Various advantages and objects of the present invention will be brought out more particularly in the following description:

In the drawings, Fig. 1 is a face view of a visible index construction in normal position, to which my invention is applied.

1 to 7 of the drawings, 1 designates the central web, and 2 the flanged or channelledl side guides of a metal frame of standard construction now in extensive use. The flexible hanger 3 may vtake theV form of resilient lengths of wire extending across the central web 1 of the frame and having spaced returnbent ends upon which the hinge elements des! ignated as a whole 1 are placed.`

The hinge elements may comprise two substantially flat metal plates 5 and 5a connected by means of connecting rod 6 which in the present instance is constructed of a substantlally non-flexible material. On opposite outer edges of each pair of plates 5 is a spaced return-bent lip 7 forming the means for locking the cards in place. As shown `best in Figs. 1, 2 and 3, each plate 5 may be bent at one end to form a bead 8 and each plate 5a may be bent at one endrto form a bead 8a provided with a longitudinall opening 8,. A second closed bead 9 may also be formed adjacent the beads 8 and 8a. The beads 8 and Samay com'- prise the means for removably attaching plates 5 and 5a to hanger 3, while the closed beads 9 may constitute the means for permanently attaching plates 5 and 5a to rod 6. As shown best at 10 in Fig. 6, the outer bent end of the plate 5b may be closed and may be permanently attached to the rod 6 whereas the intermediate bead 10 may be open and mzy be adapted to snap 'over the ends of the ro 3. Y

In this form, to mount the hinges upon the hanger 3, one plate 5 may be threaded upon one hanger 3. The opposite plate atmay be snapped on to the opposite hanger 3 in a manner similar to the mounting of the plate 5a upon the hanger 3 in the mo'diiicationshown in Fig. 1. f

Index cards 11 may be provided' with notches 12 on their upper side edges, said` Vcards being readily mountable on or removable'from each hinge elementby being bent centrally, the cards of course7 being iexible enough to permit this being done. 'Y y v In one of the standard structures now fin use, hinges having pintle eyesniayfbe attached von the upper edge of the cards.` These hinges are more or less permanently attached to the cards, which is of course, very desirable in certain instances. However, at other times, it has been found necessary to remove the card from the hinge, for instance, to allow the card to be rolled around the platen of a typewriter. The present invention was perfected to facilitate the removal of cards from hinges, and the arrangement described herein, accomplishes this purposev v ery readily. The cards are instantly mountable onfor removable from, theihinge element without disturbing in any way the position of the hinge. Y Y l Y I have shown one cardand hinge element in Figs. 1 and 5. It is understood ofcourse, that the cards -are mounted/in overlapping relation, ,spaced by the return-bent ends of the hangers. Y

yReferring now morev particularly to the slightly modified construction shown in Figs. 8N to 11 both inclusive, the index cards 11 instead of being provided on, their upper side edges with notches such as.Y shown at 12 in Ficht may be provided with the internal y notches 13, which notches take the form of ay slightly enlarged' circular opening 14y and an elongated narrow slot 15 extendingI inwardly from the opening 14. The plates 5 instead of being provided with locking lips 7., as are the plates 5, 5a and 5b may be provided with the locking lips 16, the construction of which is clearly shown in Fig. 11. Tomount a card 11i`n placey on the hinge element shown in this modified form of construction, it is only necessary to contract the card temporarily at its center and causeeach enlarged aperture 14 to register with thelocking lips 16, the width of the aperture 14 being sulii- `cient to allow the lockinglips 16 tov Aproject upwardly therethrough. The card is then flattened out, and the under. surfaces ofthe locking lips 16register with the s1ots15 and form a locking connection. Y

n this form the rod 6 connectingtheplates 5 is made of Vflexiblematerial instead'of being rigid as in the first form, and to mount the hinges upon the hanger 3, one plate 5"1nay be mounted upon one end of thehanger, the rod 6 connecting the two plates 5 maythen be flexedto permit the insertion of the opposite plate 5 upon theopposite end of the hanger` I" claim as my invention:
